SPECIFICATION forming part of Letters Patent No. 539,875 dated May 28, 1895.

Application filed March 20, 1894. Serial No. 504,404:- (No model.)

.Ta aZZ whom it may concern:

Be it known that we, CHARLES G. MENZEL and JULIUS O. EMMITT, of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented a certain new and Improved Barrel-Heater, of which the following is a specification. 7

Our invention relates to barrel heaters; and the objects which we have in view are to provide a barrel heater of a cheap and neat construction, and which will occupy a small floor space; the parts of which will be all interchangeable; which will have a self-centering part for holding the barrel equi-distant from the heating drum or shell; which will be economical in the use of fuel; and which will be provided with convenient draft and draft checking dampers. A last and most important object is to provide a barrel heater which will furnish an even and intense heat at all points upon the drum or shell.

Our invention consists in general in a barrel heater of the construction and combination of parts hereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a vertical section of a barrelheater embodying our invention, the base thereof being shown in full lines. Fig. 2 is a plan view of the base with the upper parts of the heater removed. Fig. 3 is a horizontal section of the base on the line w a: of Fig. 1.

- Fig.4 is a detail vertical section on the line y y of Fig. 3. Fig. 5 is a detail vertical section showing the means for decreasing the size of the heater by the employmentof a smaller drum or shell. 1 l As shown in the drawings, the base is preferably octagonal in form, consistingin the bottom 2 and the side walls 3, the front and rear sides of the octagon being cut away so that the smoke outlet sleeve casting 4 provided with the vertical grooves 5 may be slipped down into place and the door casting or frame 6 similarly secured. The door casting is provided with a level face adapted to receive the lid or door 7, the upper edge 8 of which, when the door is in place, rests in the groove 9 provided in the top casting 10 of the base. Within vided with the vertical wings 16, used to increase the heating surface of the fire-pot, whichfire-pot is made of cast iron.

, On the upper edge of the lower section 15, we arrange the upper section 17, the inside of which preferably flares and enlarges toward the top. Thelower edge is preferably strengthened by the bead 18, and has a groove so that it fits down nicely over the thin upper edge of the part 15. The openings in the top casting 10 and within the ring 13 are of less diameter than said ring, so that a shelf is formed to receive the grate ring upon which the grate 20 rests.

The ring 19 raises the grate abovethe cast- 7 greater Openings 25 in the top 10, and between the ring 13 and the rib 24 form diving fiues leading intothe space or chamber 26 within the base and around the ash-pit walls. These openings 25 preferably occupy about one-half of the full circumference of the annular opening within the rib 24, parts 27 being. left to support the ring 13 and the grate,

The shell 22 fits down upon the top 10 and outside of the rib. 24.. and is preferably of about one and one-half times the height of the fire-pot. metal, and the top thereof is closed by the cast- This shell is made of thin sheet- IOO ing'29, which has a central opening closed by the door 30, which door may be of any desired construction.

For furnishing air to the gases in the upper sand and the casting made without thense part of the shell we preferably provide the small inlet channels 31 in the lidcasting 9, forming the'same beneath simple bases 32 on said casting, and cutting the groove down through the flange 33 thereof, so that the pattern for said casting may be drawn from the of cores.

In the front sections of the octagonal base we preferably provide openings 34 and arrange the check dampers 35 for closing the same. Through these air may be let into the chamber .26v to check the draft of? the/stove.

ported on a flange or'legs 38 restingon the top of the base and theringis provided with the tapered inner flange 39 which fits snugly to the shell2 2, and by means of whichthe barrels are'centered on the'rest 37. T

For use with smaller barrels the heater is accfo'mpanie'd by a smaller shell with a barrel rest having an innerepe'ningbf correspond} ingly'decreased size. For this piu'rpe'sewe provide the reducing ring 40, See, Fig. 5 A

similar reducing ring rii'ayalso be'used beneath a smaller fire-pot. Thebase of this ring 40 rests a'rou nd the rib 24 while the upperedg'e supports the smalle r shell or'drum ll'. 37 represents a correspondingly reduced barrel rest. A stoveof this construction occupies avery small floor space and owingf'tfo the usefof the narrow annular diving lines-between the outer walls'of the fire-pot and'the shell 22," insii'res anintense and'eve'n heat on the full surface of said shell; further the nicest regulation may be obtained, the stove ni'ay'be easily fed with fuel, and further the castings hf, which the stove is formed are small and complete in themselves, of regular sizesandhonseqn'ently interchangeable. As shown in Figs. 1 and 5 we provide a firepot having thick wallsj'atbr near its base, tapering gradually towardthe top of the'pot, so that at thepoint whereth e' heat of the fire will be most intense the potlwill be thicker and will not'burn'oiit as rapidly aslit would if it were made thes'ame th'ickne'ss at the'top and bottom. Having thus described our invention, we claim as new and desire to secure by Letters Patent i 1.
